SKI COASTER Filed March 8, 1929 0 8 y f M w W Z w N WM r. F c W- 15expensive construction, is com-posed of the Patented June 9, 1931 CARLE. B. GUNDERSEN, EN

rwis'rnn, YALBERTA, GANADAJ v .sKI-ooAsrEn Application filed March 85This present invention relates to new and useful improvements in aski-coaster and has for its primary object the provision of a sim-' pleand inexpensive structure in which both the forward and rear skis arehingedly mounted on the upstanding frame so that they may properlyengage the surface and reduce to the minimum, liability of breaking,unnecessarily straining or injurying any of the parts of the structureor the connections between such parts. i

Another object of the invention resides in the provision of aski-coaster of the character stated which is of extremely simple andinminimum number of parts and includes a strong frame composed oftubular members firmly connectedwith one anotherand supportingadjustable steering handles and an adjustable seat, whereby the devicemaybe adjusted to suit the requirements of the description proceeds, myinvention resides in the construction, combination and arrangementofparts as shall be hereinafter more fully described, illustrated in'theaccompanying drawings and pointed out in the claim hereunto appended.

The invention will be best understood and can be more clearly describedwhen reference is had to the drawings forming a part of this disclosure,whereinlike characters in- I dicate like parts throughout theseveralviews.

In the drawings I Figure 1 is an elevation of the improved ski-coaster;and Y 7 Figure 2 is an enlarger detail cross section, takensubstantially on the plane ofline 22 thereinthe-(upper:v end of theforward =upiez'a Serial No: 3 15379. I

Referring more in detail to the drawings,v it isuto :be' noted-that theframe includes transverse upper member 6 on which the seat" 7 is 1mounted;- foralongitudinal adjustment thereof,1by suitable mountingmeansBwhich is adjustable alOngtheImember.6.2 A collar I 9 is acarriedat the ,rearend of the upper frame member ,6 {and the upper-extremity pof the rear upstanding frame i-me'mber '10, is

secured, .inathe collary9lf "A. similar collar elliis' carried on theforward ,.end .of. the

pp r frame; member B and :has', working standing f ramefmember{'12.Thebearing collar;l'3 is secured on the frame 'me'mberli just below; thecollar, 11, by. aqsetscrew 14 or the like. The upstanding handle anporting bar-l5 is adjustable-vertically init e upper end of the framemember 12' and-also rotatablyv adjustable therein. A 's'etz'screw 16 isemployed for-securing the handle-supporting bari iii-adjusted positionand the :di- 'verging handl-eubars 17 are; secured on :the!connection-18 carried at the upper extremity of the-handle supportingbajr15, appropriate hand 1 grips -1 '9*being;carried on the free ends ofthe handle bars 17. The lower end ipor-' tionsoffthe forward upstanding;frameniem- :ber12 is-rotatable-in the-collar 2O carriedon the lower endof. the rear'wardly inclined frame bracing member21, on thevupper end ofwhich is carried th e'collar .22 surrounding and firmly secured on therear upstanding frame member 10, near the upper; end thereof.

.The framebracing member 21 carries laterall-y directed.footrests- 23nearits lower: end for engagement bythe "feet of-- the coasterwhenco'astingdown inclines. A. pair of stop collars-24;.are secured onthe =.forward frame membcrsl2 above and; below the collar: 20 1 toprevent independent vertical movement .of-the frame member 12 or-thecjollar 20.1

-Each of the upstanding frame :members 10 andlzfhas a bearing lug; 25',depending centrally ,fromits lower extremity 26 which is rounded or;convex from front to back on either side, of thei dependingvlug 25; -tens ersepireebo t- QZ seX endedt rQu h each lug and also throughupstanding bearing lugs 28 carried on the upper face of a bearing plate29, which latter is secured by suitable securing members 30 on theraised or thickened portion 31 of a ski runner 32. The rear ski runner82 is considerably longer than the forward or steering ski runner 32. Itis also to be understood that the rear ski runner 82 is not capable ofturning toeither v side but the forward ski runner 32 is turned byoperation of thehandle 17 L As the construction of the device has thusbeen described in detail, brief referenceis now had to its use and modusoperandi: The handle supporting bar 15 is adjusted in the forward frame.member 12 andt'secured in adjusted position by the setiscrew .16. Theseat 7 is also adjusted on the upper frame member 6 and the device ispropelled by the feet, except when going down inclines atwhich timesthefeet may be placed on the foot rests 23. The steering device isaecomplished by the handle bars 17 and owing to the pivotal mountingof'the ski runners 32,

.they may readily give either forwardly or rearwardly of theirrespective pivotal mountings vvhentravelling over uneven surfaces,

thus eliminating danger of injury to the device. All of-the framemembers and the frame bracing member may be constructed of tubing asdisclosed or a board of appro- 'priate widthmay be substituted for theupper framemembe-r 6ZLI1Cl other parts of the frame structure altered asrequired.

From the foregoing description taken in connection with-the accompanyingdrawings, it will be manifest that a ski-coaster is provided thatwill-fulfill all the necessary requirements of such a' device, but as"many changes could be made in the above description, and many apparentlywidely different embodiments of my invention may be constructed withinthe scope of'fthe'appended claim without departing from the spirit orscope thereof, it is intended'tliat all matters contained in the saidaccompanyingspecificaframe member; said upstanding frame members alsobeing connected by an incline' frame bracing member attached to the'upstanding rear frame memberlnear the upper e def the latter and mountedon the upstanding, forward frame member nearthe lower end there of; eachof said upstanding frame members havinga rounded lowerextfrem'i'tyfwitha central lug depending therefrom; a pivot boltextended transversely through each or said r lugs; forward and rearwardskirunners having raised portions intermediate their ends;

and bearing plates carried on said raised portions With pairs ofupstanding bearlng lugs; one ofsaid pivot bolts being extended throughthe pair of upstanding bearing lugs of one of said bearing plates.

In testimony whereof I hereunto aflix my signature.
